I'm am using table rate to give discounts to customers in the surrounding states. To give a discount I have set it up so that a negative amount of money is given per money spent. This works up to the third entry in the table. It effectively gives a discount based on shipping address, but it fails to change the discount value after the second table entry.


Here is the table.

300:-50,600:-100,900:-150.00,1200:-200,1500:-250,1800:-300,2100:-350,
2400:-400,2700:-450,3100:-500,3400:-550,3700:-600,4000:-650,4300:-700,
4600:-750,4900:-800,5200:-850,5500:-900,5800:-950,6100:-1000,6300:-1050,
6600:-1100,6900:-1150,7200:-1200,7500,-1250,7800:-1300,8100:-1350,
8400:-1400,8700:-1450;9100:-1500, 9400:-1550,9700:-1600,10000:-1650

Once the discount reaches $100 it does not change for larger totals.

Any help would be appreciated. Can table rate just not handle the negative values?

Thanks.
